Please setup the Dip-switches before the device powered on.</p><p>6</p><p>Raisecom Technology Co., Ltd</p><p>3.3.1.</p><p>SW1</p><p>1st bit Switch of Ethernet interface auto-sensing. On=Close auto-sensing capability. Off=Open auto-sensing capability (default). When the auto-sensing capability of Ethernet interface is opened, the auto MDI/MDIX capability is opened at the same time. Ethernet interface has 10/100M auto-sensing capability. If connected Ethernet interface mode of switch, hub and network-card is fixed, then the Ethernet working mode of RC952-FEE1 is half-duplex. When the auto-sensing capability of Ethernet interface is closed, the auto MDI/MDIX capability is closed at the same time. The Ethernet working mode of RC952-FEE1 is determined by 2nd bit and 3rd bit switch. 2nd bit: 10/100M setting switch of Ethernet interface On=10M Off=1001M (default) The switch is invalid when 1st bit switch is off. The switch determines Ethernet interface rate when 1st bit is on. 3rd bit: Duplex mode switch setting of Ethernet interface On=half-duplex Off=full-duplex (default) The switch is invalid when 1st bit switch is off. The switch determines Ethernet duplex mode when 1st bit is on. 4th bit: Fault-Pass-Through switch On=Open Fault-Pass-Through function. Local LOS, LOF, AIS, CRC alarm of E1 link can disable the Ethernet interface, in order to report the link fault to switch. When there is no alarm of E1 link, the Ethernet interface resumes normal working status automatically. Off=Close Fault-Pass-Through function. There is no association between the working status of Ethernet interface and E1 alarm 5th bit: Master and slave mode switch of equipment On=Slave mode Off=Master mode (default) The switch is used for setting master or slave mode of RC952-FEE1. When RC952-FEE1 works with RC952-FEE1, one is must be set master mode and another is slave mode. When RC952-FEE1 works with RC951-8FEE1, it must be set slave mode. When the working mode of RC952-FEE1 is master mode, it can be managed by network management software. And it can manage the remote RC952-FEE1, which the working mode is slave. When the working mode of RC952-FEE1 is slave mode. Working status only can be checked by network management software, it can not be configured. 6th bit: Clock mode switch On=Slave clock mode Off=Master clock mode (default) If there is timing equipment in E1 link, RC952-FEE1 of both sites must be set</p><p>7</p><p>Raisecom Technology Co., Ltd</p><p>slave clock mode. If there is no timing equipment in E1 link, RC952-FEE1 of one site is set master clock mode and RC952-FEE1 of another site is set slave clock, or RC952-FEE1 of both sites are set master clock mode. 7th bit: Loop-back control switch On=Open loop-back function Off=Close loop-back function (default) If loop-back function is opened by Dip-switch, network management software can not disable it. 8th bit: Loop-back position switch On=Local loop-back Off=Remote loop-back (default) The switch is available only when 7th bit switch is on. Loop-back illustration is following:Local equipment</p><p>E1 Remote loop-back</p><p>Remote equipment</p><p>Local equipment</p><p>E1 Local loop-back</p><p>Remote equipment</p><p>3.3.2.</p><p>SW2~5</p><p>1st bit of SW2: Framed/unframed optional switch of E1 interface On=E1 framed mode. transmission bit rate is N*64Kbps, N=1~31 Off=E1 unframed mode, transmission bit rate is 2048Kbps (default) When the working mode of E1 is unframed (default), the 2nd~8th bit of SW2 and SW3~SW5 is invalid. These switches are available, when 1st bit of SW2 is on. 2nd~8th bit of SW2 and SW3~SW5: Switch of E1 time-slot occupation On= Occupation Off=Not occupation (default) The 31 bits switches corresponding with TS1~TS31 of E1 time-slot. When framed mode is set by user, it needs to set these 31 bits switches to select time-slot. SW2 1 TS0 ON OFF Framed Unframed 2~8 TS1~TS31 Ethernet service occupies the time-slot Ethernet service does not occupy the time-slot SW3 1~8 SW4 1~8 SW5 1~8</p><p>Note: When E1 is framed mode, it needs to ensure the switches of time-slot occupation is not all Off, at least there is one switch is On.</p><p>8</p><p>Raisecom Technology Co., Ltd</p><p>3.3.3.</p><p>SW6</p><p>1st and 2nd bit: Mode switch 1st bit OFF ON ON 2nd bit Random ON OFF Mode Mode 1 Mode 2 Mode 3 E1 is unframed mode. So the another site</p><p>When the equipment is set mode 2 or mode 3, equipment must be unframed mode.</p><p>3rd bit: Buffer size optional switch ON=Small buffer OFF=Big buffer (default) When the equipment uses big buffer, it is suitable for to transmit data service, when the equipment uses small buffer, it is suitable for to transmit image service. 4th bit: Error bits test switch On=Open error bits test function Off=Close error bits test function (default) The function is convenient for users to test network. At present, error bits test supports statistic function of ES and SES, which is stated in G.821/826 protocol. But statistic period is fixed 5 minutes (nonstandard). During the 5 minutes test period, status of error bits can be checked through network management. The equipment transmits Pseudo-Random Test Sequence at all times during the test of error bits, and service and network management control will be stopped. So when using the function, remote equipment should be set local loop-back status or local equipment should be set remote loop-back status. When applying the power supply, please note: in order to prevent between E1 line equipment potential difference oversized, for the equipment connection security. It is suggested user first connect E1 line then turn on power supply. The E1 interface should avoid hotly inserting and pulling out.</p><p>9</p><p>Raisecom Technology Co., Ltd</p><p>4.
